Listas y comentarios sobre los crustáceos decápodos de Veracruz, México

Abstract

A LIST OF THE DECAPOD CRUSTACEANS FROM VERACRUZ IS PRESENTED, DIVIDED IN THREE MAIN AQUATIC ENVIROMENTS: MARINE, WHICH INCLUDES THE LITORAL ZONE TO 200 M OR THE LIMIT OF THE CONTINENTAL PLATAFORM; ESTUARINE, COMPRISING RIVER MOUTHS, ESTUARIES, AND COASTAL LA GOONS: AND FRESH-WATER, FORMED BY ALL CONTINENTAL BODIES OF WATER, SUBTERRANEAN OR EPIGEAN, PERMENENT OR TEMPORAL. INFORMATION WAS COMPILED FROM RECORDS IN THE COLECCIÓN NACIONAL DE CRUSTÁCEOS, INSTITUTO DE BIOLOGÍA, UNIVERSIDAD NACIONAL AUTÓNOMA DE MEXICO, AND WAS COMPLEMENTED WITH PUBLISHED DATA. THE RESULTS SHOW THAT 335 SPECIES OF DECAPOD CRUSTACEANS ARE DISTRIBUTED IN VERACRUZ: 71% MARINE, 18.6% ESTUARINE, AND 10.4% FRESH-WATER SPECIES. SPECIES THAT OCCUR IN MORE THAN ONE ENVIROMENT WERE INCLUDED IN MORE THAN ONE LIST, ACCORDINGLY. SPECIES RICHNESS IN THE MARINE (261 SPECIES) AND ESTUARINE (68 SPECIES) ENVIROMENT IS CONSIDERED LOW, DUE TO THE REDUCED NUMBER OF SITES STUDIED UNTIL NOW. IN CONTRAST, THE FRESH-WATER DECAPODS, WHICH HAVE BEEN WELL STUDIED IN VERACRUZ, REPRESENT 28.8% OF THE TOTAL NUMBER OF SPECIES KNOWN IN MEXICO.
